Starting a new job after H-1 transfer

[mano8057]

So, I am in the middle of accepting a new job with employer B, but presently working for employer A. I know that its best not to quit your current employer, till you actually have the hard copy of I-797 for the new employer. I am wondering if there is a certain buffer period between a job change?

Once I have the I797 can I take my own time..after discussing with my new employer about when I can start.

Is it considered unemployment after I quit my present employer (emp A), and start working for my new employer (emp B) .....say after 2 weeks..

Considering the need to relocate and stuff..

 

 

Thanks
